Not terribly related, tho I created a source-available (not "open source" as it's Polyform Strict License) secure document viewer, which thanks to the libreoffice and other backends supports PDF, DOCX, XLSX, etc and provides a web interface where an uploaded document is converted and "images of pages" format and displayed: https://github.com/dosyago/documentspark https://github.com/dosyago/documentspark The idea is to defuse/prevent any document-borne malware vectors from infecting the device. I incorporate a version of it into the Pro version of my RBI (remote browser), BrowserBox.
